* | msm: mdss: Dither support in PingPong bufferGopikrishnaiah Anandan2016-04-28
| | | | | | | | | | | | | | | | | | | | V3 version of mdss dither block has been moved from dspp to ppb. Based on mdss revision the driver should enable the dither block in dspp/ppb. Change enables driver to handle dither block in ppb.

* | msm: mdss: register smmu context fault handlerDhaval Patel2016-04-28
| | | | | | | | | | | | | | | | | | | | | | | | Smmu context fault handler provides the fault iova information but does not provide any information about xin client. This patch registers the context fault handler in MDSS software to get the vmid/xin client information. It also dumps the registers for source associated with respective vmid client Change-Id: I2a833a4b5e81e36f4d7af23a3968c9755424b7a7 Signed-off-by: Dhaval Patel <pdhaval@codeaurora.org>
* | msm: mdss: hdmi: update power module state during probeTatenda Chipeperekwa2016-04-26
| | | | | | | | | | | | | | | | | | | | | | Update the state of any power modules that are enabled during the probe when HDMI is the primary panel and continuous splash is enabled. This allows the HDMI transmitter core to correctly power on/off modules during states transitions such as those associated with runtime suspend and resume.

* | msm: mdss: send FB registered event before initializing MDPTatenda Chipeperekwa2016-04-26
| | | | | | | | | | | | | | | | | | | | | | | | Send the FB registered event before initializing MDP in order to allow the panel driver to complete any internal initialization before MDP operations begin. For example, in the case of HDMI panels, this will ensure that the Hot Plug Detection (HPD) circuitry is enabled and that the HDCP libraries are loaded before data is transmitted on the link.

Furthermore, power on the HDMI core before enabling the scrambler to ensure that there is a smooth transition during the handoff without any temporary blinks on the panel.

| | | | | | | | | | | | | | | | | | | | Do not toggle the power for HDMI modules during continuous splash since the power would have been enabled in the bootloader. Toggling power during handoff can leave the core in a bad state especially when scrambling is enabled for 4K HDMI modes.

* | msm: mdss: fix possible race condition in mdp resource controlVeera Sundaram Sankaran2016-04-26
| | | | | | | | | | | | | | | | | | | | | | | | There might be a race condition where the early wake-up work item gets preempted for the stop call when the resource state is already set to off by the early wake-up. In this condition, the stop call clears the ctx, leading to issues when the early wake-up work item runs again since the ctx is not valid any more. Fix this condition by making sure that stop call always waits for the early wake-up work item to finish.

* | msm: mdss: modify DSI phy init sequence for split-DSI configAravind Venkateswaran2016-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For split-DSI hardware configuration, both the DSI controller clocks are sourced from a single PLL (clock-master). In such cases, it is important to initialize both DSI0 PHY and DSI1 PHY prior to enabling the PLL. This is due to the fact that for certain HW versions, PLL programming for the clock-master may require configure some PLL registers on the clock-slave. If the PHY init sequence for the clock-slave is called after PLL is programmed, it could reset those PLL registers leading to unexpected behavior. Fix this by ensuring that PHY init sequence is done for both controllers at the same time for split display usecases.

* | msm: mdss: fix mdp busy wait race conditionDhaval Patel2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DSI software does not wait for MDP_DONE ISR before sending new frame if burst mode feature is enabled. It leads to race condition in below case * MDP kicks off frame-N and mdp_busy sets to true * MDP receives new frame-N+1 and waits for PP_DONE interrupt before sending N+1 frame. * MDP receives PP_DONE interrupt and kicks off frame-N+1 (DSI_MDP_DONE interrupt is not received yet). * Frame-N+1 kickoff sets the mdp_busy wait to true. * DSI receives DSI_MDP_DONE interrupt for frame-N and reset the mdp_busy to false. * Any clock off call can turn off the clock at this moment. DSI software must always execute busy_wait when kickoff happens from mdp. That avoids the busy wait race condition.

* | msm: mdss: fix to update the configuration for display related GPIOsIngrid Gallardo2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | After commit dbe80b7cc96a1f3f23246552fbd2352f334fa857 ("ARM: dts: msm: remove gpio output settings in dsi pinctrl") driver is no longer defining in the pinctrl the gpios as output high configuration; so driver now has to explicitly configure gpio output direction. This change add the settings in the driver to configure the gpio as output pin, fixing panel issues when booting-up with continuous splash disabled.

| | | | | | | | | | | | | | | | | | | | | | In simulator panel SW-TE approach, we rely on the sync config height, init, start_pos and read ptr TE parameters. Set start_pos, init and read ptr with respect to panel yres, as it is done in the default settings when it is used with an actual panel. Setting these parameters with respect to 0 causes fps drops.

* | msm: mdss: add sysfs to generate the misr crc during interruptsIngrid Gallardo2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change add a sysfs node to enable the misr crc generation in batch mode. Once this is enabled, driver will collect the crc numbers during each of the interfaces interrupt, vsync interrupt for video mode panels and ping pong done for cmd mode panels. To enable/disable the crc generation, respectively: echo 1 > /sys/class/graphics/fb0/msm_misr_en echo 0 > /sys/class/graphics/fb0/msm_misr_en To collect the last crc generated: cat /sys/class/graphics/fb0/msm_misr_en To enable the ftrace to collect the crc for all frames: echo 1 > <debugfs>/tracing/events/mdss/mdp_misr_crc/enable CRs-Fixed: 964076 Change-Id: I47fb47b772aef097bc9af3b58a6c79565bcdc872 Signed-off-by: Ingrid Gallardo <ingridg@codeaurora.org>
